I have been using the VooDoo Labs Pedal Power 2 Plus. What I dig about it is that it can power 9V and 18V (Mu-III, and others) but can also do 24V for EHX and run Eventide, Line 6, TC Nova effects and others I can;t think of at the moment. According to Voodoo Labs. it can run any DC powered effect. It has a toroidal transformer and each of the eight power outputs is fully isolated - no noise. I noticed a big difference in the noise level of my effects when I set it up. It also has this neat feature on outputs 7 and 8 - there is a small potentiometer that you can use to drop the voltage and simulate a dying battery. I guess some people like the tone of overdrive and distortion pedals when the battery level "sags", as they say. I thought about the the DC brick but after checking out the Voodoo Labs - made in the USA, 5 year warranty, runs anything and it's dead silent, I was sold.

I got the voodoo 2 plus also. Works great but now I'm thinking the voodoo pedal power digital might have been good cause I'm eyeing that strymon möbius for modulation effects and it requires the higher milliamperes that the digital can deliver. I guess the point is you gotta look at what you want to power with it first. The 2 plus is pretty versital though and will run lots of effects.
